passing referer

[electricphp]

ok, I'm not sure if I should be posting this here or in the asp forum but here it goes.

What I'm trying to do is pass the referrer of an html page to an asp page for processing. The way I'm doing this is:

function getref(){

if (document.referrer&&document.referrer!="")
  document.write('<img src="[URL unfurl="true"]http://www.designerwebs.us/access-log.asp?pg=contact.html?ref="'+document.referrer+'>');}[/URL]

<img src="[URL unfurl="true"]http://www.designerwebs.us/access-log.asp?pg=contact.html&ref=javascript:getref()"[/URL] border="0">

There are 2 problems. the first is that the function is not invoked, it simply passes javascript:getref() instead of the output of the function.

The second problem is that even if it passed the actual URL, the characters in the url such as & ? etc., would mess up the post variable. I would need the referring url to be passed in quotes or something.


On the asp page it simply gets inserted in the database as a post value.

I hope this makes sense

You can do it like this. (Why document.write seems to be used by so many so often?)

[1] script section
[tt]
<script type="text/javascript">
function getref(){
if (document.referrer&&document.referrer!="")
var obj=document.getElementById("imgid");
obj.src+="[red]&[/red]ref=" + encodeURIComponent(document.referrer);
}
}
window.onload=getref;
//other stuff
</script>
[/tt]
[2] Body section
[tt]
<img src="[ignore]

http://www.designerwebs.us/access-log.asp?pg=contact.html

[/ignore]" border="0" alt="pic" />[/tt]

Amendment

[2'] Forgotten to put the id into the img.
[tt]
<img [red]id="imgid"[/red] src="[ignore]

http://www.designerwebs.us/access-log.asp?pg=contact.html

[/ignore]" border="0" alt="pic" />
[/tt]

It is still not passing ref as a get variable. Keep in mind, the line that is invoking the asp script is this:

http://www.designerwebs.us/access-log.asp?pg=default.htm

If you mean that referrer is to appear as the querystring of the request "pq" and not as an independent request "ref", it is this.
[tt]
function getref(){
if (document.referrer&&document.referrer!="")
var obj=document.getElementById("imgid");
obj.src+=encodeURIComponent("?ref=" + document.referrer);
}
}
[/tt]
But,... requesting a .htm with querystring? well, never heard of it.

 

[electricphp]

referrer should appear as the querystring of the request "ref" so the code should be something like this:

<img id="imgid" src="[URL unfurl="true"]http://www.designerwebs.us/access-log.asp?pg=contact.html&ref=(javascript[/URL] function passes the referer here)" border="0" alt="pic" />
